General :: Ubuntu: Failure To Login With Multiple Video Adapters?
May 10, 2010
I have a computer with three video cards and six monitors. Works great on Windows. Trying to get it to run Ubuntu 10.4 as well. It loads fine when I have it configured to run on one adapter; detects both screens, runs ok. But I want to turn the other 4 monitors on and run the whole thing as one extended desktop (one session, etc). So I downloaded and installed the newest ATI driver for Linux, which seems to work, kinda. I ran this to set up the screens:
aticonfig --adapter=all --initial -f Now when I boot, Ubuntu seems to turn on all the screens (3 viewports, each with two cloned displays from what I can tell). When I enter my login info OR move the mouse off the main screen, the screens freeze and the kbd/ms become unresponsive.

I'm in a spot where my wireless access is about 200 ft from my computer so I bought a tl-wn721 adapter. I have already gotten the drivers for it but somehow I am still stuck with my wireless adapter built in to my sony vaio sz220 (yeah I know it's old...that's why I run ubuntu). So how do I change wireless adapters? The system does say that the realtek drivers associated with the 721 adapter are in use and enabled but in Win 7 I have much higher signal than what is currently displayed. Usually it's somewhere in the high 80 or 90s. Now it's hard to even get 70 and that's how I know that I'm on my built in adapter. I ran lspci -nn and this was my output. I might just not be searching for the right thing. BTW I'm running 10.04 LTS.

Like some others I have found people are having problems with network manager from time to time. It seems that wicd is the solution. Will this work with ubuntu 10.04?

Running Fedora 13 and have it working great acting as my firewall/router/samba server etc. The problem is the connection is shared by a fair number of us and the ISP is getting annoyed with the amount of torrent traffic. One of us has access to a wireless network and we'd like to figure out how to route some of the traffic through that without having to disconnect from the current network. I put a wireless card in the fedora box and can connect to the wireless but then it messes up the current network and pretty much nothing works.
At the least if I could run a torrent client (e.g. ktorrent or whatever) on the Linux box and have it download through the wireless card on tcp port XXXXX I would be happy. The torrent client and those tcp/udp ports can be dedicated to that wireless card, the rest of the network doesn't need to get involved if that makes things simpler. Not looking for a step by step tutorial, just an explanation of what needs to be done and a shove in the right direction. My experience is limited to single WAN connections up to this point.

I was having a problem with the keyring asking me for a password after I changed my user password. I googled it and found that since the password changed, I will get asked for the keyring password until I delete ~/.gnome2/keyrings/login.keyring. What happened was that I wasn't paying attention that you had to generate a new keyring password before rebooting.
Now, whenever I try to login via gdm, I get this message: error initiating conversation with authentication system - general failure
How do I get it working again? I can still login from the terminal.

I installed fedora 12.
I have 2 ATI cards that I used to use on windows to run 4 monitors. A recurring problem has been to get them detected in linux. Only my secondary card is picked up linux. When I manage the displays it detects the 2 monitors connected that card.
What are the specific steps I should take to get the second card detected? Supposedly there is a tool system-config-xfree. I don't have it, yum can't find it.
Also I heard it has something to do with editing some xorg.conf file or something to that effect. I have absolutely no idea how to find the "bus id" of my card, or lookup the horizontal refresh rates, etc..
I would probably have no problem following the documentation & editing the file if I knew a good way to find these values.
Someone also suggested installing linux twice and saving the xorg.conf it generates each time (with different card each time) and then merging the two by hand. That is like killing a fly with a hammer though, when I do this again and again in the future It'd be nice to not have to take twice as long.

In Ubuntu Lucid Lynx RC, I got NVidia's TwinView to work with 2 monitors in a single video card. But when I use the same monitors but split them between the video cards I can't make TwinView work and it starts a X server for each monitor. I want the same effect I had with one video card.

I just recently purchased a Lenovo Netbook s10 3c which I planned to use for working and such. I have always been interested in the idea of using a Linux system, and so I downloaded the ISOs for Ubuntu Netbook 10.04 and also for Ubuntu Desktop 10.04 and 9.04 as well has Fedora 13. (I wanted to try some out.)
Unfortunately, for ALL of the distros, I run into a snag. When installing any of them, my keyboard will not respond to any keystrokes, even arrow keys, enter or caps lock. I have searched on google, linux forums, ubuntu forums and lenova's site, all to no avail. It seems that everyone who is having problems is having problems with some other sort of system which involves a virtual keyboard or USB keyboard (I do not want to have to use a USB keyboard - that would silly considering I bought the thing for easy portability).

I have got a problem in the configuration of the network for my Linux box. The distribution is Slackware 12.2 with the 2.6.27.7-smp kernel. There are three ethernet NIC, one on the motherboard with Atheros AR8121/AR8113 chip and two on PCI card which with RealTek 8169.
I installed the module for Atheros which is the atl1e.ko and I defined the configuration for the three NICs in /etc/rc.d/rc.inet1.conf.
When I hit the commend ifconfig I see all the three interfaces eth0, eth1, and eth2, but the address are not distributed between the NICs as I'd like so I thought to resolve the inconvience with udev, but I don't know how to proceed because there is a strange situation.
If I control the file /etc/udev/rules.d/70-persistent-net.rules I see a strange situation: Once the file contains nonly a line for the Atheros NIC but if I reboot the system there are the two lines for the two RealTek NICs and everytime the system is rebooted there is a change between these two alternatives. A detail I noted is that the two modules atl1e and r8169 are both always loaded, so udev has always the chance to detect the hardware but for some reason that I don't know something goes wrong. Another related problem that bothers me is the absence of udevinfo and udevtest. Have I perhaps to reinstall udev?

I saw a network once that used bonding (some people called it "port trunking") to combine two network cards into a single connection to get twice the bandwidth. I have a slow Wifi network with not so great reception. I actually have two spare WiFi cards and want to try to bond them so I can get a faster intranet (not internet). Has anyone successfully bonded two WiFi cards and had pleasant results? Is there an easier way to get better bandwidth with two cards? My router and my remote machine are both running Linux.

About 1 hour after successfully installing 9.10, the window elements started flickering and were inaccessible. I was working on intalling dimdim, but I did not touch any system files around the time the failure occurred. Thereafter, any regular login attempt results in a flickering black box on top of the new dim-gray-light ubuntu login window. The machine needs to be rebooted to get out of this mode. System restore mode works perfectly. startx starts the x environment, but with the flickering and uselnessness. The machine is a dual bood Ubuntu/Vista box (yeah, I know, Vista came with it). It is an intel quad core 2.33 MHz processor. The video is a cheapo on-board type. I have included system stats at the end of this message.

I'm having a problem building some applications (e.g. Qsynth and FreeCAD) with sbopkg relating to an unfound library named "jscore". I've been keeping my system up to date with slackware64-current.Google searches have turned up very little about this library. There is a sourceforge page that has no files and seems to be related to a google hosted script jsCore.js... but I don't think that's what's missing here. I've come across some vague references to this jscore library being part of webkit. Can anyone verify this? I updated my webkit library itself and found no apparent results. Perhaps jscore was removed in an update to Qt (both of the example applications mentioned above link to Qt) as it seems to have it's own webkit library, libQtWebKit.

I just installed Ubuntu 10.10 and when I try to log in to the regular desktop environment, only the backsplash coloring is there. I can, however log into safe mode and see the GUI there. Occasionally, I will get the treat of using the regular desktop environment, but it will ultimately freeze, and if I go to a different runlevel and restart gdm, the same thing happens....only backsplash. Here's what I've looked into, all of which has failed by the way: gdm.conf, URL... even though that "fix" was for an earlier release, and of course reinstalling a few times. *Sigh*I'm running it on a Toshiba Satellite L25-S1217, Intel Celeron, 874MB RAM, and 60GB HD with the stock Radeon graphics card.

After upgrading several packages (can't remember which now) I can't login with the graphical login. It accepts the password, starts to load, but then dies and dumps me back at the login prompt again.Attempting to login from the prompt, sometimes works (there is specific condition), and when it does, I then attempt to "startx". OK, it complains the display is already in use, so I then "startx -- :1". Everything starts to load, but then fails again like the graphical login.
checking /var/log/Xorg.1.log I see no errors [EE].checking /home/***/.xsession-errors I see the following.xauth: file /home/***/.serverauth.15914 does not existI have also tried as another forum suggested and rename the .kde4 and the .skel directories to something else. Login via graphical and prompt still both fail.I have also tried logging in with another window manger. That also fails.However, I have also tried creating a new user and logging in. That works. It is from this user account that I write the postI have attempted copying over all of the application settings from the corrupted user account, but some things are missing and there are various personal project directories and permissions that are causing issues. Therefore I would like to repair the corrupted account. Where do I begin to fix the corrupted account?OS: Linux 3.0.1-40-desktop i686System: openSUSE 11.4 (i586)KDE: 4.6.5 (4.6.5) "release 4"Video: nouveau

I'm new to Debian and installed it with Cinnamon because I want to learn some OpenCL programming in Linux. I have a Nvidia GT 525M GPU. Once the operating system is installed, I followed [URL] ..... article to install the proprietary Nvidia drivers. As the forum suggested, instead of creating an Xorg server configuration file, I installed Bumblebee according to [URL]..... article.
But when I restarted my machine after completing all the steps when I try to log in I get the follwoing message:
"failed to load session 'cinnamon'"
I cannot login as normal user or root.

I've been using linux for roughly 12 years now but I've always avoided linux on the desktop since touching X back in the day was quite a hassle. I recently decided that rather than keeping my windows desktop full of 15 PuTTY instances, I should rock the *nix desktop.
I started by installing Ubuntu 10.10 Desktop. It detected my two monitors handing off a pci express card just fine. I decided to install the ATI drivers when it prompted me - the proprietary drivers would let me select to use the monitors separately, but would always just default back to mirroring the screens. I was unable to get it to stop that, so I had to go back to the open source drivers. Which is fine, I don't really need the 3d accel. Roll forward a week, I ordered another video card to add another screen. I purchased another ATI card, since word on the street is that same-vendor chipsets play best together. This one had to be PCI, if this matters.
dmesg reports the new card is fine and happy, but the Monitors GUI thing doesn't detect any monitors off the new card, or report anything about it. So: what should I do to make the second video card get noticed?[URL]...

For a while now, every time that I log back into my desktop from hard start or from restarting the X server, I get these 3 terminal konsole windows that are open on my first desktop environment. It's seems as though whatever work I was doing when I had those 3 konsole windows open got saved somewhere and is reopening them every time I get back onto the desktop. I've tried to locate the problem by looking in .bash_profile and .bashrc but to no avail. If anyone has a solution to this, that would be awesome.
